33.3mm
36.0mm
96.0mm
136.0mm
Correct answer is D
200mm ..... 100oC
Xmm ..... 60oC
400mm ..... 0oC
\(\frac{x - 40}{200 - 40}\) = \(\frac{60 - 0}{100 - 0}\)
X = 136mm
420S
336S
168S
48S
Correct answer is B
Heat energy = Elect. energy
mc\(\theta\) = power x time
2 x 4200 x (100 - 20) = 2000 x t
t = 336s
The equation PxVyTz = constant in charles' law when
x = 1, y = -1, z = 1
x = 0, y = 1, z = -1
x = 1, y = 0, z = -1
x = 0, y = 1, z = 1
Correct answer is B
According to Charles' law, the volume of a given mass of gas is directly proportional to its absolute temperature at constant pressure.
